Nws yog qhov nyuaj rau kev xav txog kev tsim kho niaj hnub no, uas tsis siv cov kab hluav taws xob ntxiv. Xws li cov ntsiab lus yog qhov tseem ceeb hauv kev tsim kho ntawm ntau yam qauv thiab qab nthab. Reinforced concrete beams kuj tseem siv rau hauv kev tsim cov tshav dav hlau khiav, kev nkag mus ib ntus, thiab hauv kev tsim cov choj. Cov khoom siv rau lawv cov khoom siv yog ruaj khov thiab tiv taus ntau yam kev cuam tshuam, ua rau cov plag tsev zoo heev. Thiab cov txheej txheem ntawm lawv cov installation yog ceev heev.
Reinforced concrete beams: production
stretched siv jacks. Cov khoom siv yog compacted siv tshuab vibration. Cov tshuaj nyob rau hauv daim ntawv hardens nyob rau hauv li ntawm 12 teev, tom qab uas cov khoom raug coj tawm mus rau hauv lub qhib cua kom consolidated nws cov khoom.
Hauv kev tsim khoom, ib qho tseem ceeb yuav tsum tau soj ntsuam: cov pob zeb sib tov yuav tsum tau muab faib ua. sib npaug li ua tau thoob plaws tag nrho qhov chaw ntawm daim ntawv. Qhob qib 200 thiab siab dua yog siv los tsim cov khoom no. Cov kab hluav taws xob ua tiav tiav tau suav nrog ntau tshaj 450 kilograms / quab yuam ib square meter.
Ntau yam ntawm Beam Structures
Tag nrho cov khoom niaj hnub muab faib ua peb pawg nyob ntawm txoj kev tsim khoom:
- prefabricated - Hoobkas ua;
- monolithic - nchuav ntawm qhov chaw tsim kho;
- precast-monolithic.
hom kab kab nrov tshaj plaws yog cov qauv sib dhos, uas yog tsim los ntawm cov qib hnyav ntawm pob zeb. Nws muaj zog txaus, muaj cov yam ntxwv siab, thiab tam sim ntawd npaj rau kev teeb tsa.
Txhim kho pob zeb hauv pem teb kab teeb GOST 28737-90: hom kev tsim kho
Nyob rau hauv kev tsim kho, muaj kev faib cov kab teeb los ntawm hom kev tsim kho:
- gable yog qhov qub thiab lattice, xaiv BSD;
- ib leeg-ntxhais ua vaj tse pob zeb yog luv luv hu ua BSO;
- rafter nrog txoj siv sia nyob mus ib txhis - BSP, thiab lwm yam.
Foundation Beams
Rau lawv cov khoom tsim, cov qib tshwj xeeb ntawm cov pob zeb yog siv, uas yog qhov txawv ntawm cov yam ntxwv siab, lossis theej, lub zog thiab kev ntseeg tau. Xws li ib tug reinforced pob zeb beam yog dav siv nyob rau hauv loj-scale industrial siv. Qhov zoo tshaj plaws rau cov cheeb tsam uas muaj kev tshee thiab siab seismic feem ntau pom. Hom kab teeb no yog tsim los rau kev thauj khoom loj heev. Lawv cov installation muab cov dej tsis zoo, tshem tawm tag nrho cov kev sib cuag ntawm cov phiaj nrog hauv av. Qee lub sij hawm lawv siv los txhim kho qhov rais thiab qhov rooj qhib.
Reinforced concrete truss beams
Pab pawg no ua ke ntau hom kev ua vaj tse pob zeb:
- ib nqes hav;
- gable.
Raws li kev teeb tsa ntawm txoj siv sia sab saud, lawv tuaj yeem tawg thiab curvilinear. Hom no yog siv dav hauv cov vov tsev, tshwj xeeb, nws yog siv rau kev tsim kho ntawm kev txhim khu kev qha thiab muaj zog qab nthab uas yuav tsum tiv taus siab loads. Piv txwv li, thaj chaw nrog cov khoom siv crane. Cov no tuaj yeem yog cov chaw lag luam nrog kev lag luam tshwj xeeb, cov tsev khaws khoom loj, cov chaw ua liaj ua teb, qhov chaw thauj khoom / thauj khoom hnyav, nrog rau lwm hom kev ua haujlwm zoo sib xws. Rafter reinforced qhob kab teeb yog nruab nrog tshwj xeeb rail fasteners uas siv los kho cov cuab yeej.
Rectangular beams
BP yog hom kab teeb uas feem ntau siv hauv kev tsim kho. Qhov nrov tshaj plaws ntawm lawv yog cov qauv tshwj xeeb uas tau nruab nrog lub txee nyob saum toj lossis hauv qab. Lub ntsiab yam ntxwv ntawm T-zoo li seem yog ib tug beam xwb. Reinforced qhob pem teb (qhov loj me tuaj yeem ncav cuag 24 m) tau sib sau los ntawm qhov ntev, qhov ntev yuav tsum tsis pub tshaj 12 meters. Hauv kev tsim kho kev lag luam, hom no suav hais tias yog qhov muaj zog tshaj plaws thiab muaj zog tshaj plaws. Kuj tseem muaj PSU nrog L-shaped seem, lawv tau tsim los txhawb facades.
Nws tsim nyog sau cia tias kev tsim kho pob zeb yog ib qho kev lag luam zoo tshaj plaws, uas tau thawb tawm ntawm kev siv cov khoom hlau loj thiab cov ntoo qub. Vim qhov kev pom zoo ntawm tus nqi thiab qib zoo, lub pob zeb muaj zog tuaj yeem raug hu ua cov khoom siv zoo tshaj plaws rau kev lag luam niaj hnub no.
